    Juicy Ulitmate Problem

    So I have had my Ultimates for about a year, and they have been pretty problematic. At first we thought pads, then alignment, then rotor, now we think it is a problem with the pistons themselves.

    Seems like they are not retracting correctly, only going back half way. They are really gummy, and just don't look to be working properly. This would explain the drag I have been experiencing, and the occasional loss of power.

    Anyone have any ideas on how to fix this? Would a bleed do it? Or do I just need to replace.

    I think this has been covered many times...search for sticky piston.
    Remove pads, squeeze lever slightly so that pistons come out of the bore...lube sticky piston with dot fluid (other have suggested silicone spray), push pistons back into bore. Repeat. That's what I do with my Juicy 7s. I don't think it affects performance, it can just create an annoying rotor drag as the pistons unequally activate with pad wear.
